FAN-BELT.

Specification of Letters Patent.

Application led May 26', Y1919. Serial No. 299,810.

To all who-m it may concern.'

Be it known thaty I, NAPOLEON J. Poivr- LANGE, citizen of the UnitedStates, residing at Minneapolis, in the county of Hennepin and State ofMinnesota, have invented certain new and useful Improvements in Fan-Belts; and l do hereby declare the following tobe a full, clear, andexact description of the invention, sueh as will enable others skilledin the art to which it appertains to make and use the same.

My invention relates to belts generally but is particularl)v directed toan improved fan belt. Fan belts. as is well known, are generally used inconnection with automobiles, for driving the fans.

(ieneraltv stated the invention consists of a novel device andcombination of devices hereinafter defined and described in the claims.

The. beltV is made up of a main body of leather or other suitablebeltin; material and a heavy backing of felt. rI`he leather body isprovided with several laterally spaced longitudinal rows of perforationsthat open dire tl \Y against the felty backing.

ietween the rows of perforations and on theouter side thereof theleather belt and the felt backing are connected by rows of stitches. i

ln the accompanying drawings which illustrate the invention likecharacters iudicate like. parts throughout the several views.

Referring to drawings:

Figure l is a. plan view of the belt portions thereof being broken away;

Fig. 2 is a sideelevation of those portions of the belt shown in Fig. l;

Fig. 3 is a plan view of the belt showing the ends thereof disconnected;and

Fig. t is a detailed view in side or edge elevation showing the elementsof the belt coupling.

T he leather body of the belt is indicated by the numeral 5 and the feltbacking thereof is indicated by the numeral 6. The numeral 7 indicatesthe rows of stitches vthat connects the leather body 5 and felt backing6. The numeral 8 indicates the perforations in the leather belt 5. Theseperfor-ations 8, in the two rows are preferably staggered so that theygive a better suction action on the pulleys.

So far as this invention is concerned, the ends of the belt may beconnected by any suitable form of coupling, but as shown the couplingcomprises two plates 9 and 10.

These two plates are riveted or otherwise rigidly secured to the ends ofthe leather belt 5, and the backing of felt (3 is terminated short ofthese plates, so that it does not overlap the secured ends thereof. The,plates 10 have a T-shaped head 10 that is 'engageable with the hook-likeoverturned ends 9 of the plate S). As stated this belt is especiallydesigned for use as a fan belt. Fan belts. as it is well known, aresubject to considerablel oil and this oil should be removed from thefaces of the pulleys.

rl`he perforations inthe body of the belt perform two functions to wit;in the first .place they give a limited suction on the. pulleys whichincrease the traction of the belt,

and in the second place they `pick up the oil might be of otherabsorbent material capa.

ble of performing the .function stated.

The stitching of the belt, it will be noted,

does not interfere with the flexibility thereof v but gives the beltincreased central strength. This' improved belt has been put into actualuse and has been found highly' etti* cient for the purpose it had inview.

What I claim is:

l. A belt made up of va body havingperloo In testimon.)Y whereof I allixmy signature in presence of two Witnesses.
